What 100 calories of your favorite junk food really looks like

• When it comes to junk foods, everything in moderation.•A 1/3 cup of ice cream is 100 calories.• Only 18 mini pretzels comes out to 100 calories.

It's happened to the best of us. You convinced yourself that just one chip wouldn't hurt. But one led to another and before you knew it, you were left with an empty bag, greasy fingertips and all the regrets.

But what did you really just put into your body? Most of us have no idea how many calories are in our favorite snacks, making it dangerously easy for them to add up. Since portion control is an essential aspect of dieting and health, being able to visualize appropriate serving sizes is a powerful skill to have.

But when you absolutely need those Hot Cheetos to get through the night, practice portion control and remember: Moderation is key.
